You don't need that. Just run the washer with baking soda in the detergent cup (use the powder setting) and in the rinse cycle, use vinegar. After that take a vinegar/water solution to wipe off the seal.
I've owned a front loading washer for over 8 years and have never bought the store crap because it is just a ploy for you to buy something that you can easily do at home. Baking Soda and Vinegar are great deodorizers (not together as they "volcano")!
